My computer Has just started acting up. I'll start up any game (Borderlands 2, Batllefield 4, Titanfall, CS:GO, FTL ,ETC.) Ranging from 1-7 minutes it'll shut th computer off. Then it'll restart but wont give me an image. I Have just recently changed the Graphics card and the power supply. My specs are

Graphics card: Geforce GTX 280 (ik it's lame but i was lowion cash.) I upgraded to that from a Radeon HD7000.
Power supply: Alienware alpha 450 watt. I upgraded to that from some offbrand 350 watt.
CPU: Intel. I dont know the name.
Hardrive. 1tb i
no ssd and i have a LG dvd drive.
WIndows 8.1

Please help!!!

SO the problem was that my graphics card was draining too much power. Thus the shutting off. I took it out and used an onboard graphics card on the motherboard. I tried borderlands 2, it ran but at 2 frames per second (exaggeration) gameplay was shit. Is there any way for me to be abkle to use that graphics card and have it NOT drain that much power?
